FIELD: agriculture.
SUBSTANCE: group of inventions relates to agriculture, in particular to milking equipment. A valve node of an applicator of nipple treatment fluid contains a pipeline for nipple treatment fluid, first valve (902) for closing the first end of a flow path, second valve (908) for closing another end of the flow path, a source of nipple treatment fluid under pressure, communicating via fluid with the flow path, when the first valve is closed, and the second valve is closed, and device (912) for tracking pressure, communicating with the flow path for determining fluid pressure in the flow path. The node of the safety valve of the applicator of nipple treatment fluid contains safety valve (900A) controlling fluid for pre-milking nipple treatment, and safety valve (900B) controlling fluid for post-milking nipple treatment.
EFFECT: compactness of a safety valve, and ease of tracking for possible leakage are provided.
